We moved when my son was nearly one so I didn't know anyone in the area, and I couldn't find a playgroup - everyone seemed to have their own friends and were closed to anyone new. I dont need the stimulation (I'm antisocial too ) but was worried about DS. Now I take him to Art N Move on Tuesdays and swimming lessons on Thursdays (he's 2) and the rest of the time we keep busy with dad and big brother and I try to take him to the park and softplay. He's outgoing and happy and we didnt' really start any classes until he was over 1. At this age at the park they just fight over toys anyway.
